Python - WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 127

The error "WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 127" indicates that the ChromeDriver process terminated unexpectedly, and the exit status code was 127. Exit status code 127 usually means that the executable (in this case, chromedriver) could not be found or executed.

Here are steps to resolve the issue:

  1. Ensure ChromeDriver is Installed: Download the appropriate version of ChromeDriver from the official ChromeDriver website: https://sites.google.com/chromium.org/driver/

    Make sure to place the chromedriver executable in a directory that is included in your system's PATH.

  2. Specify ChromeDriver Path in Code: If you don't want to rely on the system's PATH, you can specify the path to chromedriver directly in your Selenium code:

    from selenium import webdriver # Replace "/path/to/chromedriver" with the actual path to chromedriver executable driver = webdriver.Chrome(executable_path="/path/to/chromedriver")

  3. Check System PATH: Ensure that the directory containing chromedriver is in your system's PATH. You can check the PATH environment variable:

    echo $PATH

    If the directory containing chromedriver is not in the PATH, you can add it:

    export PATH=$PATH:/path/to/chromedriver/directory

  4. Check File Permissions: Ensure that the chromedriver executable has the correct permissions to be executed. You can use the chmod command to set the executable permissions:

    chmod +x /path/to/chromedriver

  5. Update ChromeDriver: Ensure that you are using a version of chromedriver that is compatible with your Chrome browser version. If your Chrome browser has been updated, download the corresponding version of ChromeDriver.

  6. Use WebDriverManager: Consider using the webdriver_manager library, which can automatically download and manage browser drivers. Install it using:

    pip install webdriver_manager

    Then, in your code:

    from selenium import webdriver from webdriver_manager.chrome import ChromeDriverManager driver = webdriver.Chrome(ChromeDriverManager().install())

  7. Check for Other Errors: Look for other error messages or stack traces in the logs that may provide more information about the issue.
